Answer:

Total income= $2,614.4

Step-by-step explanation:

Giving the following information:

Workweek hours= 40

Total salary per week= $653.6

First, we need to calculate the monetary value of an hour:

Earn per hour= total salary/number of hours

Earn per hour= 653.6 / 40

Earn per hour= $16.34

Now, the total income for 4 weeks:

Total income= 653.6*4

Total income= $2,614.4

Answers

Answer:

X = 40

Step-by-step explanation:

{ 2 (x + 10)} = (3x - 30)

2x + 10 = 3x - 30

10 = 3x - 2x - 30

10 + 30 = 1x

40 = 1x

X = 40

What is an equation of the line that passes through the point (2, -5) and is parallel to the line
6x + y = 6?

Answers

y=-6x+7 or 6x+y=7 if you need the same format.

The required equation of the line is 6x + y  = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

What is the slope of the line?

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

First, we have to determine the slope of the line 6x + y = 6 by placing it into a slope-intercept form:

6x + y = 6 ⇒ y = -6x + 6

Therefore, the slope of the line is m = - 6

Since the required line passes through the point at (2, -5).

Let the line  (y - y₁) = m(x -x₁  )

Here x₁ = 2, y₁ = -5

Substitute the values in the equation,

So, y - (-5) = -6(x - 2)

⇒ y  + 5 = -6x + 12

⇒ 6x + y  = 7

Hence, the required equation of the line is 6x + y  = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

The cost of the family’s cell phone plan rose from $130 to $194 when they added a phone for their daughter. What was the percent of increase?

Answers

Answer:

49%

Step-by-step explanation:

Step one:

initial price=$130

final price=$194

Step two:

we know that the percent increase is given as

% increase= final-initial/initial

substituting we have

% increase= 194-130/130*100

% increase= 64/130*100

% increase= 0.49*100

% increase= 0.49*100= 49%

therefore the percent increase is 49%

what is the answer to this..√25x+10=15

Answers

x = 1.

Step-by-step explanation:

√25x + 10 = 15

√25x = 15 - 10

√25x = 5

squaring both sides:

(√25x)^2 = (5)^2

25x = 25

hence x = 1.

Answers

Answer:

We set up 2 equations:

n - m = 80 so "n" is the larger number

A) n - m = 80

B) m / n = .6

A) n = 80 + m

B) m = .6 n   so B) n = (5/3) m

We substitute B) into A)

(5/3) m = 80 + m

(2/3) m = 80

m = 1.5 * 80

m = 120

Answers

Complete Question

Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph, use their z-scores to find which dog is running faster relative to its breed

Answer:

Miniature dachshunds is faster

Step-by-step explanation:

From the question we are told that

   The speed of the Miniature dachshunds is  [tex]x = 14.8 \ mph[/tex]

    The mean for the Miniature dachshunds is [tex]\mu_1 = 13 \ mph[/tex]

    The standard deviation for the Miniature dachshunds is  [tex]\sigma_1 = 1.6 \ mp h[/tex]

    The speed of the Labrador is [tex]y = 25 \ mph[/tex]

     The mean for the Labrador is [tex]\mu_2 = 22 \ mph[/tex]  

    The standard deviation for the Labrador  is  [tex]\sigma_2 = 2.8 \ mp h[/tex]

Generally the z-score for the Miniature dachshunds is

     [tex]z_1 = \frac{x- \mu_1 }{\sigma_1}[/tex]

=>  [tex]z_1 = \frac{14.8 - 13 }{1.6}[/tex]

=>  [tex]z_1 = 1.125[/tex]

Generally the z-score for the Labrador is

     [tex]z_2 = \frac{x- \mu_2 }{\sigma_2}[/tex]

=>  [tex]z_2 = \frac{25 - 22 }{2.8}[/tex]

=>  [tex]z_2 = 1.071[/tex]

From the value obtained we see that  [tex]z_1 > z_2[/tex] , hence miniature dachshund  is  faster

Answers

Answer:

as the last two months have a few minutes in a factory and we have a few minutes away and will also send the

7x + 4y = 24
4x - 4y = 0

first thing we need to do is eliminate a variable by adding them together. 4y - 4y eliminates the y.

7x + 4y - 4y = 24
4x - 4y + 4y = 0

7x = 24
4x = 0

no we can add our x’s together since they are the same variable.

11x = 24

now we need to divide both sides by 11.

11x = 24
— —
11 11

x = 24

11

this is x. now we need to substitute x into our first equations.

4(24/11)-4y = 0

then solve the equation for y. y in this equation is y = 24/11.

possible ordered pair is (24/11, 24/11) but we need to substitute this ordered pair into our equations.

7(24/11) + 4(24/11) = 24
4(24/11) - 4(24/11)= 0

both of these equations are true, meaning that the ordered pair is correct.
